Depends where the computer got its data.
If the data came from the same speed sensor the car's speedometer uses (a sensor on the transmission), then the moment the car left the road the rear wheels would be spinning on grass or whatever else he was traveling over.

If the black box used the input from the ABS system, that should be based on 3 or 4 sensor that measure actual wheel speed.

Typically the black boxes record the last 5 or 10 seconds before an air-bag deployment event. 5 seconds would be a long time at 75mph (~100 ft per second). So you should be able to trend the data and correspond that with the maximum acceleration of the car.

I suspect a 300hp Crown Vic would take quite some time to go from 75mph to 105... like 10 seconds. I base this on the belief that the car's 0-100 times are on the order of 17 seconds (and I suspect never reaching 100mph in those 17 seconds).

The "black box" is typically part of the air-bag system (determines when to deploy so it measure G-forces, speeds etc.)
On older GM cars its typically under the driver's seat. If you smash the main computer (again, older vehicles behind the dash, more comonly now in the engine compartment) you will be breaking the wrong box.

Just remove the airbags and install real seat belts. (note both of these are illegal. As for installing good seatbelts, you must keep the old, DOT approved, ones intact to remain legal.) Air bags, are part of 'passive restaints' that, despite what is advertised, is made for dopes that don't use seat belts. DOT approved seat belts are designed for comfort, not protect. They are much too narrow for the speeds and energies that you could see at highway speeds.

My best notes were actually in pen.... more precisely a multi-colored pen. Black for subject headings, blue for text, green for examples, red for important stuff. I have very good memory recall for things like that and it worked well for me. A combination of actually writing down the notes, plus a vivid image in my head what the notes looked like, I found it really easy to recall exactly where in my notes a subject was covered.
The problem I have with electronic note taking is that I have little concept on approximately where in my notes something is.. Was it on page 10, 20 or 30? With a physical notepad, I always had a rough idea.
Of course I'm older, and my brain never grew up on I-pads.

Comment Easy - RFID (Score 1) 170

Contestants (be it cars, people whatever) have an RFID tag (probably passive, 900Mhz RFID) in a name tag or other tag (tag on dash of car) that will give you decent interval timing.

For the finish line, or where timing is more critical, you can supplement with a camera (photo finish if you will).

900Mhz RFID is typically good for 15+ feet (depending on the size of the tag) and can be used reliably up to about 45 feet (big tag on big metal object - like a rail car). Tags can be very cheap - about 25 cents. To 'track humans' you need to keep the tags off the skin (skin detunes/absorbes RF energy) so you need a slightly thicker name tag (foam backed) for reliable reading at range.

Oh, and its already been done. I believe runners right now use a low frequency RFID tag tied to their shoe laces and they have to run over a mat. Low frequency RFID is based more on magnetic fields - thus short range only.

As for cheating, the top competitors in a marathon are watched pretty carfully and their are lots of witnesses. The people running it for themselves.... well who cares if they cheat. Sorta like using an aim-bot on single player mode.

Comment Re:Astrolabe, Inc. v. Olson et al (Score 1) 433

If this in fact goes any further.
The defendant's lawyers are going to argue that there is no specificity in the lawsuit. They will ultimately ask the plaintiffs exactly which elements were copied and why, again with specificity, do the plaintiffs believe they have the copyright. The plaintiffs will try to song and dance around the fact that this is just 'facts'. Might be interesting to hear how they will spin this.

The gist of the article is that MS believes their consultant found some dirt on Android and it's code, which Google seems to think will be very damaging to it's (Motorola's) case, and as a result, all Android devices.

You have to understand how lawsuits work. Team A says they want to get the defendant's middle name, Team B, although they don't see the harm, they move to block it because they will not give Team A a single sliver of evidence that isn't specifically needed.

I was involved in a lawsuit where our lawyer actually blocked the subpoena of meeting minutes - which we had and which we believed supported our claim - because it wasn't necessary (you could just subpoena all the people that were there). Had me worried because the recollection of other people in the meeting seemed to be 'off' (against us). At trial, our lawyer the opposition's story went wild (the exaggerated, lied, made up things etc.) and our lawyer beat them up over it. "You were quoted saying this to the newspaper, you said this in your deposition, and now you say this at trial. Which version is the truth?"

Bottom line, limit the other side's information, limit what they can present in court, and finally, limit the arguments they can make. Chess is a lot easier if you whittle it down to just a few pieces left on the board.

Amazon expressly does not use roads and transportation in Kalifornia. Other companies do - like UPS. And those companies pay to have their trucks registered, pay for fuel (which is heavily taxes), pay taxes on tires, on wages, and if you've ever dealt with the weigh stations, they pay taxes simply by entering the state.
Essentially Kailifornia does get revenue from everything sold into Kalifornia - they just want more revenue - and they want an out of state company to collect it for them.

What if Kalifornia thinks Amazon is not paying enough? Are they going to issue warrants for Bezzos's arrest? Bottom line, Kalifornia has no jurisdiction over Amazon and couldn't enforce the tax if they wanted to. What are they going to do? Ban imports from Amazon?

Comment Re:Infected RFID tags (Score 1) 59

In fact, passive RFID chips are so small and dense (and designed in USA or Europe) there is no room for extra functionality. At best there would be a dozen or so extra transistors sprinkled around. When you are trying to make millions of devices, the more chips you can pack on a wafer yeilds more profit. Also, every extra transistor affects sensitivity.

Finally, these RFID tags are read by a reader. So in theory, one attack vector could be SQL injection. ID lengths are like 96 bits. Not a lot of room for a SQL inject attack.

Now most of these mass produced are built on old tech fabs in East Asia. As the technology matures the ID lengths get longer and longer to the point that one day there might be enough room for more. Right now, nothing to worry about.

Comment I've ridiculed IT staff for not supporting Linux.. (Score 1) 432

Seriously, IT is a support service.

To paraphrase someone else:
"No one has an 'IT' problem" The might not be able to get financial reports, projects etc. out in time. One of the tools that could help might be an IT asset, but its only a tool. The end goal is to deliver something.

Now if the IT person says "look, we don't have the skill set or bandwidth to actively support 3 completely separate OS's" O.K. then. That's an answer, pay more, go on your own, or adopt their supported system.

If your an English major, get the supported system. If your computer science or related engineering, go on your own. (Run one of each).
